The flag of Marche is one of the official symbols of the region of Marche, Italy. Like many Italian regional flags, it was adopted on 4 November 1995 for Armed Forces Day of Italy. In absence of a law on the subject, the regional emblem that had been adopted on 15 March 1980 was simply inserted on a white background.

Marche, in English sometimes referred to as the Marches, is one of the twenty regions of Italy. The region is located in the central area of the country, and has a population of about 1.5 million people, being the thirteenth largest region in the country by number of inhabitants. The region's capital and largest city is Ancona.
